Question

我正在用cocos2d做一个游戏，我有一个骑士角色，我想改变它的精灵。所以在我的knight.m中，我这样做了：

- (id)initWithKnightPicture {

        l1 = [NSString stringWithFormat:@"knightL3.png"];
        l1_plist = [NSString stringWithFormat:@"knightL3.plist"];

        self = [super initWithFile:l1];


    if (self) {

                [[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:l1_plist];

        // ************* RUNNING ANIMATION ********************
        animationFramesRun = [NSMutableArray array];
        for(int i = 1; i <= 6; ++i) {
            [animationFramesRun addObject:
             [[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName: [NSString stringWithFormat:@"Level1-Run-hd-%d.png", i]]];
        }
    }
    return self;
}

- (void)update:(ccTime)delta
{
    if ([[GameMechanics sharedGameMechanics] game].fatness < 20) {
        l1 = [NSString stringWithFormat:@"knightL1.png"];
        l1_plist = [NSString stringWithFormat:@"knightL1.plist"];
    } else if ([[GameMechanics sharedGameMechanics] game].fatness < 40) {
        l1 = [NSString stringWithFormat:@"knightL2.png"];
        l1_plist = [NSString stringWithFormat:@"knightL2.plist"];
    } else if ([[GameMechanics sharedGameMechanics] game].fatness < 60) {
        l1 = [NSString stringWithFormat:@"knightL3.png"];
        l1_plist = [NSString stringWithFormat:@"knightL3.plist"];
    } else if ([[GameMechanics sharedGameMechanics] game].fatness < 80) {
        l1 = [NSString stringWithFormat:@"knightL4.png"];
        l1_plist = [NSString stringWithFormat:@"knightL4.plist"];
    } else if ([[GameMechanics sharedGameMechanics] game].fatness < 100) {
        l1 = [NSString stringWithFormat:@"knightL5.png"];
        l1_plist = [NSString stringWithFormat:@"knightL5.plist"];
    }
}

所以基本上，我希望骑士的精灵根据骑士的肥胖从knightL1.plist变为knightL2.plist ......所以我在我的代码中所做的是，我正在指派骑士成为字符串l1，并在l1中将l1_plist和knightL3指定为init。然后在我的更新方法中，我将l1和l1_plist更改为不同的字符串。问题是，如果胖度超过80，并且我将l1和l1_plist字符串更改为不同的字符串，则精灵不会从knightL4.plist更改到knightL5.plist。那么我怎样才能让骑士随着比赛的进展而变化呢？

提前致谢！

您发布的代码应该有效。尝试在胖子＆gt;的调试器中单步执行它。 80并查看执行的行。

在init-cocos2d中更改sprite plist文件
